Method for removing spur interference of WIFI system, computer storage medium and broadband system

The invention discloses a method for removing spur interference of a WIFI system, a computer storage medium and a broadband system. The method comprises the following steps: acquiring an input signal; in the time domain, multi-stage spur interference removal processing is sequentially carried out on the input signal, and the spur interference at least comprises direct current offset interference, HDMI interference and CW interference. According to the method for removing the spur interference of the WIFI system, the influence of the spur interference signal on the performance of the receiver can be well eliminated, and the problem that the receiver cannot work normally due to the fact that the spur interference signal is too large is solved. 本发明公开一种去除WIFI系统spur干扰的方法、计算机存储介质和宽带系统，该方法包括：获取输入信号；在时域内，对所述输入信号依次进行多级去除spur干扰处理，其中，所述spur干扰至少包括直流偏移干扰、HDMI干扰和CW干扰。本发明实施例的去除WIFI系统spur干扰的方法可以较好的消除spur干扰信号对接收机性能的影响，避免spur干扰信号过大引起接收机无法正常工作的问题。
